KANT E A ADMIRAÇÃO DA NATUREZA

RESUMO: O parágrafo 62 da Crítica do Juízo, cuja função é definir o conceito de conformidade a fins objetiva (objektive Zweckmässigkeit), começa com uma declaração do filósofo segundo a qual todas as figuras geométricas se relacionam com uma conformidade a fins objetiva e admirável. Embora não seja aqui essencial para a definição do princípio dessa conformidade a fins, a afirmação de Kant de que ela é muitas vezes digna de admiração exerce um importante papel para a sua própria definição. O objetivo deste texto é tecer algumas considerações em torno dessa relação entre o princípio estritamente lógico da conformidade a fins e o sentimento em geral, seja de admiração da natureza, ou em todas as suas variações, tais como aparece na sequência do mesmo parágrafo 62: o entusiasmo, a alegria e a estupefação. Embora de antemão se reconheça que tais sentimentos não podem intervir no mecanismo estritamente lógico desse princípio, que, segundo Kant, é transcendental, pretende-se mostrar como o seu uso relaciona-se sempre e de algum modo com um sentimento. Para isso, é preciso mostrar que a afirmação de Kant segundo a qual o juízo teleológico não possui nenhuma relação com o sentimento de prazer e desprazer não implica necessariamente que esse tipo de juízo não possua relação nenhuma como nenhum tipo de sentimento.

Identification and Validation of Brazilian Chronic Pain Descriptors

Appropriate pain assessment is very important for managing chronic pain. Given the cultural differences in verbally expressing pain and in psychosocial problems, specific tools are needed. The goal of this study was to identify and validate Brazilian pain descriptors. A purposive sample of health professionals and chronic pain patients was recruited. Four studies were conducted using direct and indirect psychophysical methods: category estimation, magnitude estimation, and magnitude estimation and tine-length. Results showed the descriptors which best describe chronic pain in Brazilian culture and demonstrated that there is not a significant correlation between patients and health professionals and that the psychophysical scale of judgment of pain descriptors is valid, stable, and consistent. Results reinforced that the translations of word descriptors and research tools into another language may be inappropriate, owing to differences in perception and communication and the inadequacy of exact translations to reflect the intended meaning. Given the complexity of the chronic pain, personal suffering involved, and the need for accurate assessment of chronic pain using descriptors stemming from Brazilian culture and language, it is essential to investigate the most adequate words to describe chronic pain. Although it requires more refinement, the Brazilian chronic pain descriptors can be used further to develop a multidimensional pain assessment tool that is culturally sensitive.

A psicologia redescobrirá a sexualidade?

O senso comum indica o psicólogo como o profissional mais preparado para trabalhar com a sexualidade. Raramente, entretanto, formamos psicólogos para lidar com a vida sexual em contextos que não sejam clínicos. Esse artigo sintetiza uma crítica às abordagens "sexológicas", dominantes no século XX, argumentando que a abordagem "construcionista", ao desconstruir a heteronormatividade e a subordinação da mulher como naturais, validou-se como paradigma alternativo de grande relevância para a pesquisa e a prática de profissionais que abordam a sexualidade. O construcionismo interpretou melhor novos desafios, como a epidemia da Aids, especialmente em contextos de desigualdade e violação de direitos, inspirando a prevenção baseada na análise de gênero e compreensão de cenários, cenas, scripts e trajetórias de sujeitos sexuais. O trabalho dos psicólogos será beneficiado se sua formação redescobrir a sexualidade, repensar a sexologia, superar abordagens baseadas em valores pessoais e em psicologias com pretensões universalistas, ao menos no campo da sexualidade.

Ultrasound detection rate of single umbilical artery in the first trimester of pregnancy

Objective To determine accuracy of first trimester detection of single umbilical artery (SUA). Methods The number of vessels in the umbilical cord was examined in a prospective cohort of 779 singleton, low-risk, unselected pregnancies, in the first (11-13 weeks) and second (17-24 weeks) trimesters, using both power and color Doppler and after delivery, by placental histopathologic exam. Concordance between first and second trimester findings to postnatal diagnoses was compared by calculating kappa coefficients. Results There was medium concordance between the findings in the first trimester and the postnatal diagnoses (kappa = 0.52) and high concordance (kappa = 0.89) for the second trimester scan. Sensitivity, specificity, positive and negative predictive values for the findings in the first trimester were 57.1, 98.9, 50.0 and 99.2% and for the second trimester were 86.6, 99.9, 92.9 and 99.7%. Conclusion Sensitivity and positive predictive value of first trimester scan to identify an isolated SUA in a prospective unselected population was poor. Diagnosis of isolated SUA as well as a definitive judgment about the presence of associated anomalies would still require a scan in the second trimester. Copyright (C) 2011 John Wiley & Sons, Ltd.

Neurodynamics of an election

Variables influencing decision-making in real settings, as in the case of voting decisions, are uncontrollable and in many times even unknown to the experimenter. In this case, the experimenter has to study the intention to decide (vote) as close as possible in time to the moment of the real decision (election day). Here, we investigated the brain activity associated with the voting intention declared 1 week before the election day of the Brazilian Firearms Control Referendum about prohibiting the commerce of firearms. Two alliances arose in the Congress to run the campaigns for YES (for the prohibition of firearm commerce) and NO (against the prohibition of firearm commerce) voting. Time constraints imposed by the necessity of studying a reasonable number (here, 32) of voters during a very short time (5 days) made the EEG the tool of choice for recording the brain activity associated with voting decision. Recent fMRI and EEG studies have shown decision-making as a process due to the enrollment of defined neuronal networks. In this work, a special EEG technique is applied to study the topology of the voting decision-making networks and is compared to the results of standard ERP procedures. The results show that voting decision-making enrolled networks in charge of calculating the benefits and risks of the decision of prohibiting or allowing firearm commerce and that the topology of such networks was vote-(i.e., YES/NO-) sensitive.

Stigmatization of alcohol and other drug users by primary care providers in Southeast Brazil

This study reports on the views of Primary Health Care (PHC) providers in Southeast Brazil on the use of alcohol and other drugs which reflect stigma, moralization, or negative judgment. Six hundred nine PHC professionals from the Brazilian states of Sao Paulo and Minas Gerais took part in the study. The majority (86.5%) of these professionals were female. Attitudes toward the use of alcohol and other drugs were evaluated in comparison to Hansen`s disease, obesity, depression, schizophrenia. HIV/AIDS, and tobacco use. The use of tobacco, marijuana/cocaine, and alcohol were the most negatively judged behaviors (p < 0.05). Nursing assistants and community health care workers demonstrated the severest judgment of alcohol use. In addition, marijuana/cocaine addicts and alcoholics suffered the highest rate of rejection by professionals. The hypothesis that the use of alcohol and other drugs is a behavior stigmatized by health professionals being confirmed, it is important to develop strategies for changing provider attitudes in order to provide a higher quality of service to these patients. This study is important as a first study among PHC professionals about social stigma of alcohol and other drugs users. (C) 2009 Elsevier Ltd. All rights reserved.
